The Swing Caddie SC300i Launch Monitor is a standalone device that offers instant feedback for each and every shot you take. It will measure carry distance, swing speed, ball speed, and smash factor and return these results on the 5.3" LCD display. It even provides ball flight metrics usually only found on more expensive monitors. The SC300i connects directly to a personal phone or tablet via Bluetooth on the new MySwingCaddie V2 App allowing golfers to track their real-time integrated data. There are no additional fees, no hidden costs to use this product. It is portable and comes with remote control for ease of use, and provides voice distance output.
